Everybody gets 50 twollars, and can write to get more...
Printing money in this cavalier a manner really should lead to hyperinflation, which means I'd really hate to be one of those businesses that committed to matching the funds with US dollars. But perhaps it won't be a problem, since the US Treasury is printing US Dollars at a high rate as well lately, so perhaps the two inflation rates will match, negating any ill effects.
It seems like this idea depends on whether it can provide sufficient exposure/traffic for the sponsors, which could be hard. In the end, isn't the value of a twollar just how much traffic that tweet will bring back to twollars.com to the sponsors ad/brand?
In the next version we'll be offering a whole suite of new ways for the sponsors to benefit from Twollars. Including an API which allows them to send the Twollars they buy from a charity to their users. I'll be releasing more details on the blog in the coming weeks.
